Snow plow



Patented July 26, 1938 UNITED STATES PATENT (')FFICEA SNOW PLOWApplication November 3, 1936, Serial No. 109,040 In Switzerland November23, 1935 2 Claims.

The object of the present invention is a snow plow of which the plowingwheels are constructed to work on the peripheries and over the wholeworking surface are as far as possible equal to 5 the size of thesurface to be cleared, the plowlng wheels having the form of drumsprovided on their periphery with scoops forwardly inclined to the axisof rotation and arranged to collect and condense the snow and to ejectthe same through ejecting orifices or tunnels.

An example embodying the invention is illustrated in the accompanyingdrawing.

Figure 1 shows the snow plow in side view, one of the plowing wheelsbeing shown in cross section.

Figure 2 shows the plow in plan.

The tractor I is provided at the front with two drum-like plowing wheels2 mounted side by side in a housing open at the front face upon ahorizontal cross-shaft 2 which is adjustable in height and power-drivenin the direction of the arrow, the means for achieving these resultsbeing only diagrammatically indicated in the drawing. Thus, for example,the shaft 2a is adjustably held in two vertical slots l0 of the frameand carries a gear Il for its connection with the motor drive of thevehicle.

'I'he scoops 3 mounted on the periphery of the wheels 2 are at their midparts parallel to the axis of rotation and at both ends inclinedforwards in the direction of rotation. They can however be of full Vform, i. e. without the parallel mid parts, and constitute in all casesa kind of convergent milling-cutters, so as to collect and condense thesnow during operation.

During forward movement oi the tractor the scoops I of the wheels engagethe snow and impart to it, owing to the action of the end parts of thescoops I extending obliquely from the outside to the center line of theperiphery of the plowing wheels, a relative movement thereon so as todrive it from the sides towards the mid' parts 4 and 5 of the twowheels, from whence it it conveyed to the snow ejecting funnels 6 and 1provided at the rear of the above said housing 5 so as to be thrown outtherethrough with the aid of the intervening centrifugal action.

If the layer of snow upon the street surface is to be cut away, a shield8 removably arranged under each wheel is removed so that when the l0cross shaft la has been lowered the wheels can act upon said layers.

As it may be seen from the foregoing, the described device acts in factas a. rotary snow cutter and thrower. l5

What I claim isz- 1. A snow plow comprising a housing open at the frontface, plowing wheels therein in form of a drum mounted on a horizontaltransverse axis and arranged to enable the whole rectangular 20 frontface of the snow plow to be cleared, inclined scoops on the periphery ofsaid plowing wheels and snow ejecting funnels on said housing, saidscoops extending obliquely across a certain part of the periphery of theplowing wheels so 25 as to impart to the snow a relative movementthereon to drive it towards the discharge opening of said ejectingfunnels and to centrifugally project it therethrough.

2. A snow plow comprising a housing open at 30 the front face, plowingwheels therein in form of a drum mounted on a horizontal transverse axisand arranged to enable the whole restangular front face of the snow plowto be cleared, inclined scoops on the periphery of said plowing 35wheels and snow ejecting funnels on said housing, said scoops beingV-shaped so as to condense the snow while driving it towards thedischange opening of said ejecting funnels.
